Question 75.

Answer 75. Let CP of chair = Rs x
Let CP of table = Rs y
according to condition 1
125x/100 + 110y/100 = 1520
or 125x + 110y = 152000
or 25x + 22y = 30400 ........... (i)
according to condition 2
110x/100 + 125y/100 = 1535
or 110x + 125y = 153500
or 22x + 25y = 30700 .............(ii)
Solving by any method we get
x = 600, y = 700
CP of chair = Rs 600
CP of table = Rs 700
